Title: Starter for synchronous motor
Inventor: YOKOTA HIROSHI
IPC: H02P1/46
Filed: 1979-02-12
Abstract: PURPOSE: To restrict the voltage rise of a lowered voltage applied to a synchronous motor and the voltage drop of a bus due to the opening of a bus circuit when starting the motor within an allowable range by limiting the energization of an excitation setting potentiometer to desired range at the lowered voltage time.  
     CONSTITUTION: When a start command is dispatched, a lowered voltage breaker 4 is closed, and a lowered voltage is applied to a synchronous motor 1 to accelerate the motor 1. When the speed of the motor 1 becomes predetermined value, a field breaker 16 is closed, a changeover switch 12 is closed at an excitation setting potentiometer 13 side wherein the excitation of the motor at the lowered voltage is set at desired range such as, for example, 0.8∼0.9P.U, and field current is flown through a field winding 1a to synchronize and pull in the motor 1 at the lowered voltage. Then, the breaker 4 is opened, a full voltage breaker 3 is closed after predetermined time when the phase becomes coincident, and the switch 12 is switched to an automatic voltage regulator 11 side. Thus, the voltage rise of the lowered voltage and the voltage drop of a bus due to the opening of the bus circuit can be restricted to an allowable range when starting the motor.

Title: Temperature detector
Inventor: HOSOI KIYOO
IPC: G01K7/24
Filed: 1981-02-05
Abstract: PURPOSE:To detect the temperature at a high accuracy with reduced level of a self-generated heat of an element varied in the impedance depending on the temperature by applying a voltage to the element intermittently. CONSTITUTION:A pulse generator 9 interrupts the current of a stabilizing DC power source 2 by opening or closing a switch gear 11 such as analog switch depending on a rectangular pulse fed from a synchronous signal generator 10. Interrupted current is applied to a thermistor 4 through a bridge circuit 3. A detector section 12 detects a voltage value of the thermistor with the bridge circuit 3 and amplifies 5 it. A synchronous detector 13 as a sampling hold circuit holds an output voltage of a differential amplifier 5 until the subsequent pulse is input by the same pulse as the rectangular pulse fed to the switch gear 11 from the synchronous signal generator 10 and outputs it to an output terminal 14.

Title: Automatic setting device for pid constant
Inventor: ENDO TOSHIO
IPC: G05B13/00
Filed: 1987-01-23
Abstract: PURPOSE:To simply obtain the characteristics of a controlled system with high accuracy at a point near the target value by using a means which differentiates the control deviation and a pre-tuning means which decides the increase of time so that the changing rate of the control deviation is set larger than a prescribed level. CONSTITUTION:A differentiation means 15 differentiates the control deviation obtained by subtracting the controlled variable supplied to a controlled system 14 from an ON/OFF control means 11 from the target value. A pre-tuning means 17 decides the increase of time so that the changing rate of the control deviation is set larger than a prescribed level. An arithmetic means 16 receives input of the output of the means 15, the decided increase of time and the control deviation and calculates a PID constant of the controlled system. A PID control element 13 sets and controls the PID constant calculated by the means 16. Thus the control deviation is differentiated at a time point when this deviation is equal to zero and the increase of time is decided so that the changing rate of the control deviation is larger than the prescribed level. In such a way, the characteristics of the controlled system can be obtained simply and with high accuracy at a point near the target value.
